More traffic will not increase your rankings in search engines. Google frowns upon paying for links - so they would certainly dislike you paying for traffic.

The traffic you bought will likely be bots or people who were scammed into clicking a link. These people will probably not be the kind of traffic you are looking for, and your bounce rate will be close to 100%.

I would be extremely careful buying services like this. Any black-hat or paid link-building scheme out there that go against Google's guidelines could potentially harm your rankings.

The very first thing that I would ask the traffic seller is about the referrer information of the traffic. Have seen many of the traffic sellers online and used many of them for SEO experiments. Almost all of the cheaper ones drive traffic from PTC or PPV ad networks, some of them spoof the referrer information to look like coming from organic searches.

To cut short the story, traffic like like will be of no use if not harmful (which it can be sometimes) from an SEO standpoint as this traffic will be almost all the time stale and is of no use. Would like to mention that the bounce rate of these types of traffic can be sometimes very impressive and looks very legit. This might be because of the ad networks' rules as to earn credit, they visitor should be on the page for so and so time and should browse at least so and so number of pages before exiting.

I have also seen that such traffic can be used to improve the Alexa Rank in many cases. Other than this, I have not seen any considerable advantages related to these kind of traffic sold by many so called traffic sellers online (the cheaper ones). Forgot to mention that most of these traffic will look either "direct" or some ad server's IP or host name in web analytics.

If you are selling blue widgets then you really only want people that are looking for blue widgets, no use directing people who are not interested. As for ranking No, it will not help.

What does help is and sort of related, is clicks from search engines, Bing and now Google track users that use the search engine in the way that. If a user goes to Bing or Google and searches for blue widgets and clicks on result #1, then returns and clicks on #2, and does not return, then that is a signal that #2 is a better result for the search term. if this happens enough then #2 will replace #1.
